When you think they touched the basics, they come with something you already forgot. And all the good SM things done with the right amount of pain.
Let's go daddy.

There was one years ago, a shonen, that was uncomfortable and not this open in sex, it was just for sm. When it is sm with a contract and not just "let's be violent", they tend to have spoken rules and stop words.
I know that all of the sm don't have to be painful, but it was good to understand the "good part" of this SM world. Then you can find those who prefer no rules and just have hardcore sex

I have seen several stories already where mls try to fix what they did in the past. Some of them are unforgivable, but as the story develops, they still make you think there is a possibility, because the ml in question isn't the same dude from before, and to send you the vibes of "you should be forgiving".
Sorry, but nope. Even if your ml is always black haired and cannot change, it would be great to see a story where the ml tries hard, gets a "ok, you're forgiven", but doesn't end up with the female lead in the end.
You can try to create this type of environment. It seems more difficult, since all the stories go about almost the same, and if you make the black haired male lead being punished and not forgiven, or forgiven in the end but not married with the FL... That would be NEW :D
I still love these stories, but it seems that some people in the comments know already where this is going and they do not like it XDDDDD

You should read Duchess of The Attic. She does exactly this. When the husband matures and thinks he can ask for forgiveness. Spoiler the ML is the childhood friend.
